First IUI Failed...

Hi everyone. So I had my pregnancy test done today via blood work 14 days after my first

IUI

and it came back negative. I didn’t realize how much it would affect me to be honest, but it has.

My question is that my husband has a low sperm count. Post wash was 5.2 million. Upon reading things online, it continually comes up that with numbers that low,

IUI

is a lost cause and

IVF

is the only way to conceive. Does anyone have any successes with

IUI

and low sperm count? I don’t want to keep spending money on something that has a zero success rate.

Thanks.
